LFEBOAT.

Application led December l0, 1923. Seriali No. 679,855.

T0 all I207mm z' 97mg/ concern.'

Be it known that I, MARTIN FRANZ Maren, a citizen o't the United Statesot Americay residing at Seattle, in the county of King and State ci`Washingtom have invented oei tain new and useful improvements inLiteboatsr oiI which the following is a specication.

This invention relates to improvements in life boats involvin T the useof a single keelson and the disposition of the floor 'trames of suchheight and in such relation to the keelson as to provide compartmentsfor storing water and food containers, or the loose equipment oit thelife boat.

The invention further provides the sides ot the boat of suchconstruction as to provide for the convenient housing of air tanks orother buoyant material containers.

The invention also provides the use of thwarts, which are removablysecured in a manner to insure against the spreading of the sides of theboat and to include a substantial stanchion support for the thwarts asrequired in boats ot this type.

The invention is illustrated in the accompanying drawings, in which:

Fig. l is a broken view in vertical longitudinal section of the improvedboat.

Fig. 2 is a transverse section thereof illustrating particularly themounting for the thwarts.

Fig. 3 is a sectional view showing the means designed in connection withthe improved lite boat to permit nesting of the boats.

The improved liie boat which aside from the details hereinafter referredto, may be constructed in any usual or preferred manner, includes alreelson l, extending longit-udinally and centrally of the boat to there-l spective ends thereof, with which keelson is connected theappropriate member of transversely arranged iioor tinlbers 2, to whichlatter may be secured the bottom 3 and floor 4; of the boat. The floortimbers extend transversely relative to the keelson' and are oiilsuliicient height or depth to provide a series of spaces 5, between thekeelson, licor timbers, bottom, and floor of the boat, to receivecontainers as 6 for the storage of food, water and the like, whichspaces are also adapted to receive any appropriate loose equipment forthe life boat.y

The sides of the boat have the usual rib timbers 7 secured to the loortimbers by metallic knees 8, on the outer side of which ribs arearranged the usual side walls 9, and on the inner side in spacedrelation the usual battens l0, the latter being in spaced relation asindicated. The ribs are ot sufficient dimension transverse the boat toprovide in thc side walls between the ribs a series of compartments orspaces 1L in which may be placed air containers, indicated at l2. orcontainers with cork or other buoyant material. whereby to provide formaintaining the buoyancy of the boat when in use.

Secured on the appropriate batten on each side of the boat are thwarts18, these latter being removably held in connection with the particularbattens by dowel pins 14h which may be conveniently 'forced intoposition or removed therefrom at will. The thwarts are Jfurther securedin position by substantial rods l5, having a hinge or swivel connectionwith the underside oi: the thwarts adjacent the respective ends thereof,with the free or lower ends of the rods formed as hooks 16, to engage ineyes l? secured to the side of the boat. As the thwart-s are more orless permanently secured in place by the dowel pins. it is apparent thatthe sides of the boat will not spread. and hence the rods 15 may be ofsuch length as to tightly engagethe eyes l?.v whereby the rods act ineii'ect as stanchion supports for the thwarts, as is required in thisJtype oi boat.

ln order to provide a sutlicient number of lite boats to accommodate themaximum number ot passengers ot a vessel without re quiring excess spacefor the storage of such life boats, it is necessary that the life boatsshould be nested. and to secure this result a supporting thwart 1S isprovided in the boat below and preferably between the main thwarts, thesupporting thwart being removably secured in position by dowel pins 19engaging blocks 2O secured. between or. to the appropriate battens.rlhese supporting thwarts are in such position as to permit one lifeboat to be nested and supported in another in a manner to permit theirconvenient separation when required for use. Obviously in the nesting ofthe life boatsi the main thwarts will be removed, being convenientlyreplaced when the life boats are to be used, as will be evident.

Claims:

l. A life boat havingthe main thwarts secured to the walls or the boatby removable dowel pins, rods extending from said thwarts to the sidesof the boat; and removably eoliueeted to such eides, the connection ofthe rods between the thwarts und boei; providing e substantially rigidStructure to Seive ne stanehion suppoi'ts for the thwai'ts, and nSupporting' thwart removably secured to the sides of the boat below themain thwai'ts and arranged at such height above the bottom of the boatas to receive and support the bot- 10 tom of a nesting boat..
